I know that. It would probably even work with another pak size (in pak128, planes and rivers are compiled as pak of size greater than 128). My question is about graphical and economical consistency. Regarding that, trains cannot be compatible with both paksets as Standard's tracks are lower than Britain's tracks. So your train looks like it's hovering. By the way, in my opinion, the graphical style of your addon makes it more fit to pak128 Britain than Standard. Also, graphical length doesn't match dat length, vehicles'images are overlapping each other.
